microGiGaCN™ FCN- 260 (D) Series
The MicroGigaCN offers a cost-effective I/O
solution for high-speed applications in data and
telecommunications convergence (voice, data,
video and storage). It utilizes a 2.5 Gbit/sec wire
speed connection with four or twelve wire link
widths, offering a scalable performance range of
500Mbps to 6Gbps per link to meet the needs of
entry-level and high-end enterprise systems.
Forward crosstalk is less than 4% at 100 pico
second pulse-rise time (four-pair switching).
Fujitsu Components designed the
MicroGiGaCN to specifically address the emerging
requirements for a high speed differential signal I/O
connector. The MicroGiGaCN offers a unique
solution to LVDS, InfiniBand TA, 10G Ethernet, 4x
Fiber Channel, and other high speed I/O
applications. InfiniBand has selected Fujitsu’s
connector for the 4x and 12x I/O connector
interface.
The performance requirements of the
connector system were tested with cable to
simulate the actual requirements of an OEM
System manufacturer. Our test data includes the
parasitic effects of the PCB, along with
measurements of a completed I/O cable assembly.
Electrical Performance in out testing:
•
•
Matched Impedance:
93.6 to 109.9 ohms @ 100 ps Trise
Low Cross Talk:
NEXT 3.8% @ 100pc Trise (4 pairs switching, 2 connectors and 10
meters of cable)
•
•
•
Low Insertion Loss:
2.3dB @ 2.5Gb/s (1.25GHz, 1 Meter Cable Assembly)
Skew within Differential Pair:
14.2ps (2 connectors and 2 meter of cable)
Skew pair to pair:
21.2ps (2 connectors and 2 meter of cable)

Fujitsu Components has designed the
mechanical features of the connector to provide space
saving footprint that will allow for 3 4x I/O connectors to
mount onto a PCI form, or 2 12x. As RFI/EMI are
critical elements in high performance cable assemblies,
Fujitsu Components provides the surface mount
sockets with an EMI Ground Spring on the face of the
connector, to insure that the metal surface of the
connector makes sufficient contact with the metal face
of the card bracket.
The latching mechanism of the backshell offers
a lanyard system for ease of un-mating the I/O plug
connector/cable assembly from the SMT I/O socket.
The die cast backshell offers excellent RFI/EMI
characteristics. The backshell uses a ferrule and

unique ground spring system to provide 360 degree
contact of the cable shield to the backshell, which,
combined with the solid interconnect of the socket to
faceplate, offers low AC coupling termination.
The current version of the I/O plug comes
with an attached paddlecard for wire termination.
Fujitsu will offer the paddlecard in either an
equalized or un-equalized version (see factory for
details of the equalized version). Standard product
offering will be un-equalized. As there are multiple
applications for the paddlecard, with industry and
customer specific wire termination, Fujitsu
Components offers options to customers of providing
the I/O plug connector with custom paddlecards
(consult factory).
